Lithium ion batteries have a lot of advantages over other batteries, including:

Elevated energy density. Lithium ion batteries store more energy than other types of batteries for a similar sized battery, enabling ultra-high power densities far exceeding current lithium-ion technology.

Excellent charge efficiency. Due to smart charging algorithm implemented by the BMS, lithium-ion batteries lose less energy throughout the charge/discharge cycle than other battery types (Battery Management System). Many of the useful when huge amounts of energy are now being stored (as with EVs and solar technology storage).

Higher than normal discharge power. High power battery pack with high power cells provide high power on demand to power electric vehicles (EV) and sustainable energy storage systems.

Reduced self-discharge. Although low self-discharge NiMH batteries can be obtained, lithium-ion batteries are obviously low self-discharge.

Very high cell voltage. Which means that fewer cells in the series string have to generate a given voltage that may easily power devices.

Extremely safe and thermally stable. Intelligent BMS is critical to lithium battery performance; it works as the battery’s brain, responsible for advanced monitoring and management to ensure safety, performance, charge rates, and long lifespan.

It can be lightweight. Lithium ion batteries are significantly lighter than other chemistries to get a given size and quantity of energy storage (including Lead acid battery). This is particularly ideal for applications like EVs or small portable devices.
